Even Trump seems unable to stop Trump, though it sometimes feels as though he’s trying harder than anyone. It’s not your everyday candidate who can, in the space of two weeks, still sit atop the polls after picking up endorsements from both Louis Farrakhan and David Duke, after retweeting a Mussolini quote, after dismissing with the wave of a hand a charge that his campaign manager assaulted a young woman reporter, and after offering to pay the legal fees of a supporter caught on-camera sucker-punching a protester (whom the supporter later suggested might need to be “killed”).

Let’s think through Trump, Murphy says. “He doesn’t understand the presidency. You don’t call up the head of Mexico and say, ‘Hey, I’m going to build a fabulous wall with first-class gold toilets and you’re gonna pay for it.’ You don’t call up the head of the Ford Motor Company and say, ‘You can only manufacture things in the U.S. or I’m going to unilaterally impose tariffs.’ He has no understanding of presidential powers. He has no understanding of Congress. It’s like putting a chimp in the driver’s seat of a tractor. He’s not going to plow the field. He’s going to drive the tractor into the lake. So the stakes are high. And having problems is not a license to vote stupid. People need the tractor to plow the damn field, now.”

The EU and Turkey reached a deal to stem the flow of refugees and quickly return many refugees who are now in Greece to Turkey. The EU will accept Syrian refugees directly from Turkey, and Turkey will receive €6 billion and be granted visa-free EU travel starting in June. It’s not clear if the deal abides by international and EU law, and Greek and Turkish domestic laws will have to be changed.
